The Sea Tech company continues to develop design and technical solutions for vessels of the Alfa model range with a passenger capacity from 6 to 250 people. The model range includes hydrofoils equipped with an innovative canard foils system.

About Canard Hydrofoil System

The main advantages of the "canard" design with a load-bearing aft wing, compared to the traditional "aircraft" design for our country, are:

- greater seaworthiness - high wave heights to be overcome without means of automatic motion stabilization;

- less overload in rough seas;

- smaller amplitude of pitching;

- less power and time to enter hydrofoil mode;

- ease of implementation of raising both bow and stern foils for movement in shallow water or approaching an unequipped shore.

The canard hydrofoil design is currently successfully used for a number of hydrofoil boats, such as the Sokol (BMB-14) and Marlin (Project ST11H).

The original advantage of the wing system of the Marlin hydrofoil is the kinematics of folding/extending the foils, which ensures the movement of the boat in shallow water. This scheme was developed with the participation of the outstanding design engineer Valentin Volkov (RF Patent 208645).

The hydrofoil design according to patent 208645 was first implemented in the project of a boat with lifting hydrofoils - project ST11H. Chief designer - Valery Shcherbakov.

Developing the direction of high-speed vessels, Sea Tech began to develop multi-hull vessels with dynamic unloading hydrofoils (vessels of the Hysucat type). The work is carried out by an international team, including specialists from Russia, Australia, Germany, Turkey and South Africa.
